Part Name(s) : TEA1751LT NXP
NXPNXP
Description : HV start-up DCM/QR flyback controller with integrated DCM/QR PFC controller

General description
The TEA1751LT is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1751LT combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components.

Part Name(s) : RT9259A RT9259AGS RT9259APS Richtek
RichtekRichtek
Description : 12V Synchronous Buck PWM DC-DC and Linear Power Controller

The RT9259A is a dual-channel DC/DC controller specifically designed to deliver high quality power where 12V power source is available. This part consists of a synchronous buck controller and an LDO controller. The synchronous buck controller integrates MOSFET drivers that support 12V+12V bootstrapped voltage for high efficiency power conversion. The bootstrap diode is built in to simplify the circuit design and minimize external part count. The LDO controller drives an external N-MOSFET for lower power requirement.

Part Name(s) : RT9228CS Richtek
RichtekRichtek
Description : Advanced PWM and Dual Linear Power Controller

General Description
The RT9228 is a 3-in-one power controller optimized for high-performance microprocessor and computer applications. The IC integrates a synchronous buck PWM controller, a linear regulator, and a linear controller as well as monitoring and protection functions into a 24-pin SOP package. The PWM controller regulates the microprocessor core voltage. The linear regulator provides power for the clock driver circuit and the linear controller regulates power for the GTL bus.

Description : Synchronous Rectifier Controller With Ultra-Low-Standby Current

The UCC24630 SR controller is a high-performance controller and driver for N-channel MOSFET power devices used for secondary-side synchronous rectification.
The combination of controller and MOSFET emulates a near-ideal diode rectifier. This solution not only directly reduces power dissipation of the rectifier but also reduces primary-side losses as well, due to compounding of efficiency gains.
